BEAM on POLE STRUCTURE.-

Applieation filed June 21, 1926, Serial No. 117,502, and in Canada March 6, 1925.

This invention has relation to certain new and useful improvements in a beam or pole structure and has for the primary object the provision of a simple form of beam .or pole which may be readily assembled from stock and the parts firmly united to form a beam or pole which willstand considerable transverse strain without showing local dis-' tress at any point.

The invention has for another object the provision of a beam or pole structure of the character stated which is inexpensive and which may be readily transported with the parts disconnected if desired and then quickly assembled.

The invention has for a further object the provision of a beam or pole structure of the character stated including rolled T-members specifically set forth, claimed and shown in,

the accompanying drawings forming a partof the present application and in which- Figure 1 is aplan of a pole constructed in accordance with the present invention.

Figure 2 is an elevation thereof with the central portion of the pole broken away.

Figure 3 is an enlarged fragmentary transverse section showing the construction of one of the T-member's and a form oflattice or connecting member secured thereto.

Figure 4 is a detail perspective of the lattice or connecting member employed in the form shown in Figures 1 to 3 inclusive.

Figure 5 is a fragmentary elevation of the modified form of theinvention.

Figure 6 is a transverse section thereof substantially on-the plane of line VIVI of Figure 5, looking in the direction indicated by the arrows.

Figure 7 is a detail perspective of one of the lattice or cross members employed in the form shown in Figures 5 and 6.

Figure 8 is a view similar to Figure 5, showing a further modified form of the invention. I

Figure 9 is a detail transverse section substantially on the. plane of line IXIX of Figure 8, looking in the direction indicated by the arrows.

Figure 10 is a detail perspective of one of the lattice or cross members employed on in the form shown in Figures 8 and 9.

Figure 11'is a transverse section of a further modified form of the invention.

Referring more in detail to the drawings in which similar reference characters desigea nate corresponding parts throughout the several views, it will be noted that the beam or pole structure includes a pair of opposed rolled metal T-members 15 which are positioned with respect to one another, when assembling the beam or pole, so that their stems or webs 16 are dire ctedtoward one another but suitably spaced for connection by the lattice or connecting members 17, as shown in the drawings. It will also be seen from the drawings that the lattice or connecting members 17 are preferably arranged diagonally, with the alternate members 17 inclined oppositely in the manner of forming lattice work structures. It will also be seenfrom the drawings, particularly Figures 1 andB, that the stems or webs 16 extend the full length of the T-members in Figures 1, 2 and 3 and the free. longitudinal edges of the T-members 15 are slightly turned and en larged to form rounded flanges or bulbs 15. It will also be seen in Figures 1 and 2 that side shelves 18 are mounted on the outer .faces of the T-members 15 and at their upper ends, to support the cross-arms '19 for the insulators 20, when theparts of the present inventionare assembled to form a pole such as a telegraph pole. It will be further noted from these views thatthe shelves 18 illustrated are in the form of angle irons, but this may be altered as desired.

The structure shown in Figure 2 may have angular anchor members 21 located at the bottom of the pole to assist in anchoring the pole in the ground if desired.

The form of lattice or connecting members -17 illustrated in this formof the invention are shown clearly in Figures 3 and 4, from which views it will be seen that the members 17 are of flat'rectangular form with diagprovided in the ends thereof and extending lnwardly from the outer corners on the opposite ends, as will be clearlyunderstood by referring to the drawings. Thispermits mounting of the lattice or con- 110 necting members -17. in the manner shown,, between the T-members 15, after which they may be firmly connected with the latter, in

suitable manner, as by spot welding. It

an will also be seen byreferring to Figures 2 and 3 that the slots 17 of the members 17 members 15 are connected by lattice or connecting members 23 which are rounded, as shown clearly in \Figures 6 and 7 and provided with outwardly directed slots 24 in their ends With the inner walls of the slots extended'at ,an angle with respect to the longitudinal axis of the members 23, this permitting the members 23 to be positioned in inclined planes between the T-members 15, as illustrated in Figure 5, the adjacent members being oppositely directed.

In the modified form of the invention shown in Figures 8 and 9, fiat lattice or connecting members 25 are employed with their ends 26 beveled so that the members 25 may be positioned in inclined planes with the opposed'and overlapping ends of the adjacent members 25 secured on opposite sides of the stems or webs 16 of the T-members 15 by appropriate securing members 27 such as bolts. as shown clearly in F igure'S. As the members 25 are flat and thin, it IS not necessary to provide slots in the ends thereof as in the other forms previously described.

A further modified form is disclosed in Figure 11 111 which the T-members are each formed of a pair of angles 28 opposed to "one another with parallel angles or flanges firmly united by welding or the like, this forming a firm stem :29 for each T-member. Any of the forms of lattice or connecting members shown in this application may be employed for connecting .the stems 29 of the Ts and, therefore, in Figure 11 one of the forms have been shown and designated by the numeral 30, this form of lattice or connecting member 30 being provided with straight slots 31 in its opposite ends to receive the stems 29 of the T-members. The member 30 shown in Figure 11 may represent a lattice or connecting member at or near the ends of the T-members or. a member employed at any point between the ends of the members. i

It is belEeved the complete construction and'manner of assembling the parts of the intention may be readily understood from the foregoing paragraphs taken in connec-v tionwith the accompanying drawings, Without further detailed description.

The posts may be employed as beams for flooring, upright or supporting posts and the like in building structures or as telegraph posts or in fact, in any place where a beam or post of this structure may be employed to advantage. The construction is inexpensive and the parts are constructed in. such a manner that they may be readily transported in compact form and then assembled and secured together by spot welding, or by other appropriate methods without requiring exact registration of the various parts ofthe work or expensive boring of numerous holes through the parts at exact points so. as to insure absolute registration of openings in the various members.

IVhile the preferred embodiments of the invention have been disclosed, it will be understood'that minor changes in the details of construction, combination and arrangement of cooperating elements may be re-,

sorted to within the scope of what is claimed, without departing from the spirit of the invention.

I claim In a latticed beam or pole structure, the combination of a pair of opposed rolled metal T-members, and one-piece lattice-bars extending diagonally between and. connecting said T-mcmbers. alternate ones, of said lattice-bars extending in a direction oppo- I site to the other bars said lattice-bars having diagonally slotted ends fitted over the stem portions of said T-members and permanently secured thereto.

In testimony whereof, I have hereunto set my hand.
